My invention relates to ornamental. mountings for ear attachments andfor other articles of jewelry, and particularly for the method ofconstructing such mountings. These mountings are primarily for thepurpose of engaging hollow glass shells or ornaments such as imitationpearls and beads, but may be employed for other hollow ornaments, and

such articles may be of glass.

Heretofore it was lmpossible to securely materials other thanattach'such hollow globular ornaments to an ear attachment or otherarticle of jewelry because there was not suflicient Wall thickness inthe article to furnish an adhering area between the edge of the wall andthe mounting post passing through the wall opening.

The essential objects of my invention are to overcome the abovedisadvantage in a strong and simple structure, and by an inexpensive andquick process.

My invention consists in such steps and in such successions of steps asfall-within the scope of the appended claim.

In the accompanying drawings which form a part of this specification IFigure 1 is a side elevation of one form of ear attachment in which myprocess is employed,

Figure 2, a section of the same on line 2-2 of Figure 1, j c Figure 3, asection taken on line 3-3 of Figure 2.

Figure 6, a fragmentary sectionalview of the constituent parts of themounting disposed preparatory to engagement with the ornament, and pFigures 7 and 8, additional forms of ear attachments in which my processis employed.

Like reference characters indicate like parts throughout the views.

In the drawings 10 represents the frame or.

body of an ear attachment carrying the usual convexo concave mountingplate or bearing plate 15 against whose concavity abuts a hollowsubstantially globular, frangible ornament 17 provided with a circularopening 18,

through which passes the usual mounting post 20 integral with plate 15and preferably provided with an'extern'al thread 21, or externallyroughened of irregular diameter.

The thread and roughening and irregular 1 contour of the post may beabsent, but with less desirable results. Fast to the post 20 within theornament, and engaging the adjacent portion of the inner face of theornament, is a disk or retaining member 23 which rigidly retains theornament 17 against the plate 15.

In carrying out my invention I employ a cylindrical member or disk 23 ofthe form shown in Figure 5 provided with a central hole 24. This disk iscomposed of xylonite or any'other material having similar characteristicproperties of becoming temporarily softened by treatment and ultimatelyre suming its original stiff consistency. In this specification and inthe claims the word xylonite will be understood to include celluloidand. all material possessing the. above detailed properties. This diskis placed upon the post 20. Thus assembled the parts are submerged inanacetate a sufiicient length of time to soften the disk without excessivedisintegration thereof. In practice complete submersion in the bath'for.approximately two minutes renders the disk of. suitable con-- sistencyand slightly swells it. In this condition the parts, positioned as shownin Figure 6, are manually brought together, and the disk 23, which is ofslightly greater diameter than the opening 18, is thereby forcedthroughthe latter into the interior of the ornament. The disk compactssufficiently to permit this passage. The parts are now placed at restpreferably with the post in a tilted or vertical position. After thedisk has entered the ornament the disintegrating action of the residualof the acetate continues sufficiently to cause the disk tosettle orsubside and laterally spread, since the material is now'reduced tonearly a liquid consistency. The ornament is now laid aside and thematerial of the disk in a few hours hardens upon the post andornamentwall over the opening 18 and the parts are permanently and stronglyinterengaged. V

' In "Figure 7 the frame or body 27 of the ear attachment-in which myprocess is employed is ,of the flexible type, and in Figure 8 is shownan attachmentframe' of the 'pendant'type 28 carrying an ornamentattached by my process.

In the latter the post or staple 29 is shownpassing through aperforation 3O in the platelfirather than integral therewith. Herein thepost is shown as smooth.

The process ofcombining a hollow substantially globular ornament having:an opening through its Wall With amounting plate and post, consistingin'firstplaoing upon the post a disk of xylonite of greater diameterthan the diameter of the opening, next immersing the disk in: anacetateuntil the disk is softened, next forcing the softened disk through theopening into the interior of the ornament and permitting the disk sop0sitioned to subside and spread upon the inner face ofthe Wall underthe continued action of the residual of theacetate in the disk andfinally allowing the material of the disk to reharden.

In testimony whereof I have afiiXed my 20 signature.
